<h4>
<p>
Dr. Chrisochoides' work has touched many facets of parallel and distributed 
computing. His  work includes (i) research on parallel runtime support and back-end systems for parallel compilers and problem solving environments for 
multicomputers, (ii) parallel algorithms for scheduling, load balancing, 
and data distribution for adaptive computations. He co-designed and 
implemented many key software components of a well-known simulation 
environment, <!WA3><!WA3><!WA3><!WA3><!WA3><!WA3><!WA3><!WA3><!WA3><!WA3><!WA3><!WA3><!WA3><!WA3><!WA3><!WA3><!WA3><!WA3><!WA3><!WA3><!WA3><!WA3><!WA3><!WA3><!WA3><!WA3><!WA3><!WA3><A HREF="http://www.cs.purdue.edu/research/cse/pellpack/pellpack.html"> Parallel ELLPACK </a >.
